A singly bonded amido-distannyne: H2 activation and isocyanide coordination

Abstract

The first amido-distannyne, L^†SnSnL^† (L^† = –N(Ar^†)(SiPrⁱ₃), Ar^† = C₆H₂{C(H)Ph₂}₂Prⁱ-2,6,4), has been prepared and shown to possess a very long Sn–Sn single bond; the compound activates dihydrogen under ambient conditions to give L^†Sn(μ-H)₂SnL^†, and reacts with Bu^tNC to give a stable adduct complex, L^†(Bu^tNC)SnSn(CNBu^t)L^†.
